Give the equation for Fe2+ and MnO4-
MnO4- + 8H+ + 5Fe2+ = Mn2+ + 4H2O + 5Fe3+
Give the titration equation for Cr2O72- and Fe2+
Cr2O72- + 6Fe2+ + 14H+ = 2Cr3+ + 6Fe3+ + 7H2O
What is the equivalency ratio for Cu2+ and thiosulphate (S2O32-) ions?
1 to 1
What are the 4 steps in making balanced ion-electron half equations?
1. Balance all atoms (except O and H)
2. Balance O by adding water
3. Balance H by adding H+ aq
4. Balance the charge by adding e- to more positive side
